BLUE-FLAME OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 793,032, dated June 20, 1905.

Application filed February 25, 1904. Serial No. 195,293-

To (All whom it may concern:

Be it known that l, \VILLIAM R. JEAVONS, a citizen of the United States, residing at (Jleveland, in the county of Ouyahoga and State of Ohio, have invented new and useful Improvements in Blue-Flame Oil-Burners, of which the following is a specification.

This invention relates to improvements in blue-flame oilburners of the type which cmbody an oil-vaporizing trough or bowl surmounted by perforated combustion-tubes to produce a blue flame.

The primary objects, functions, novel arrangement of parts, and the advantages thereof will be embodied hereinafter.

.ln the accompanying drawings, Figure 1 is a longitudinal vertical sectional view of a one burner stove which embodies my improvements. Fig. 2 is a relatively enlarged vertical sectional view of a burner trough or bowl, taken at right angles to Fig. l and which embodies my invention. Fig. 3 is a horizontal sectional view taken on the dotted line 3 3 of Fig. 1 looking in the direction indicated by arrow. Fig. l is a relatively enlarged detached perspective view of a burner trough or bowl, showing my present invention applied thereto. Fig. 5 is a detached perspective view of a modified form ofscrew-bearing for the oil-regulating valve.

Referring now to the drawings, 1 indicates any suitable or desired form ofsupportingframe, and 2 an oil-supply. Connected with the oil-supply is what may be termed a main oil-supply pipe or duct L is the oil-vaporizing trough. 5 represents the perforated combustion-tubes located above the said trough.

The foregoing parts and their operation whereby a blue [lame is produced are well known and well understood in this art and need no further description, except as it may be necessary to explain my present improve ments.

The form of oil-vaporizing trough or bowl is that disclosed in my Patent No. 706,06i, dated August 5, 1902, and in which there is a transverse oil duct or channel, which is open at its upper end. .\[y present invention pertains to an improved manner of supporting the burner-trough and of arranging and operating an oil-controlling valve for the purpose of simplifying the construction of the parts, lessen the possibility of leakage, to present more satisfactory conditions for the operation of the burner, and to afford convenient access to all parts of the device for cleaning purposes.

In my arrangement the burner trough or bowl a is provided with a clamp 8, which detachably clamps the trough to the periphery of the main oil-supply pipe 3. This clamp may be connected with the trough in any suitable manner and of any suitable form; but, as here shown, it is essentially U-shaped in side elevation and is connected with the trough in a manner which I. will now explain. A plug 9 is brazed or otherwise lixed to the bottom of the cross-duct 6 and preferably extends into the trough a short distance. This plug has a vertical oil-passage throughout its length, and the upper end of this passage has its wall formed into a valve-scat 11. The manner here shown of connecting the clamp 8 with the trough consists in providing the plug 9 with external screw-threzuls 12. The upper arm of the clamp has a screw-threzuled aperture 14 for receiving the scrcw-threadml portion of the plug 9. An opening 15 (preferably tapered) in the side of the pipe 3 receives the tapered or conical lower end l6 of theplug 9. Formed in the lower side of the pipe 3 is a recess 17, which receives the upper tapered end of a clamping-screw 18, which passes through the lower arm of the clamp 8. The recess 17 should be in accurate alinement with the opening 15 to support the trough 4 in a level position. From the foregoing it will be observed that the clamp comprises the U- shaped member 8, the plug 9, and the screw 18.

Main pipe 3 is usually the common iron or steel pipe of commerce, and for the purpose of insuring an oil-tight joint between the plug and the wall of the opening 15 the plug is made of a softer metal, preferably brass, which is softer and more ductile than the metal of which the pipe is composed. By reason of this and the arrangement described the screw 18 pulls the tapered end of the plug firmly to its seat and, owing to the relative yielding of the metal of which the plug is composed, conforms to any slight unevenness or inequalities of the wall of the tapered opening and insures an absolutely oil-tight joint.

In carrying out my invention a valve 20 passes vertically through the cross oil-duct 6 and coacts with the valve-seat. 11 and by means of which the flow of oil from the main pipe 3 through the passage 10 to the oil-duct 6, and hence to the burner-trough, through passages 21 is entirely cut off or controlled, as desired. The valve-stem 20 is provided with a screw-threaded portion 22, which engages suitable coacting threads formed in a block 23, suitably secured between the walls of the duct 6, or the walls of the duct may be constructed for this purpose as shown at 24:, Fig. 5. Carried by the upper end of the Valve-stem is a disk or head 25, which is constructed to interlock with any relatively movable portion of the burner. As here shown, the disk or head is provided with a plurality of shoulders 26, with which one of the connecting-rods 27 of the combustiontubes 5 is adapted to interlock, whereby a rotation of the combustion-tubes will correspondingly rotate the valve. As here shown, the combustion-tubes are adapted to be rotated through the medium of a surrounding drum 28, which may be connected in any de sired manner with the combustion-tubes. In the form here shown the drum is separated from the combustion-tubes and is supported thereon bya suitable number of vanes 29, having shoulders 30at their upper ends resting upon the upper ends of the combustiontubes 5. This drum, with its vanes, is of such size that it is removable from the outer combustion-tube, yet when in position the turning of the drum will turn the tubes, the rotation of the tubes with the drum being assured by reason of the projecting ends of the rods 27, against which the vanes will abut in cases where the drum parts fitloosely over the perforated tubes. Projecting from the drum are a suitable number of handles 31, by whichit is rotated.

The disk 25 is made to limit the amount of air which should enter the interior of the inner combustion-tube, as Well as for the purpose of turning the valve 20. In the construction here shown the disk serves as an air-regulator, owing to its size as compared to the size of the opening through the center of the trough a; but the disk may be made to accomplish this purpose in other ways, as will be readily understood by those skilled in this art.

WVith the arrangement as herein described every part of the interior of the oil-duct and oil-trough is readily accessible for cleaning. To remove small obstructions to the flow of oil, access can be had to the interior of the cross-duct 6 around the valve for dislodging any dirt therearound Without removing the trough from the pipe. By removing the trough all parts of the oil duct and valve can be reached to remove any carbon deposits or dirt. Furthermore, the valve is in such position that there is no chance forleaks and it very materially reduces the number of joints from a burner as ordinarily constructed. The construction does away with the usual soldered joints that can melt and become defective, and the structure is such that in case of any defective parts or accident anew oil-cup can be substituted by any unskilled person in a simple and efiicient manner. To facilitate the detachment and attachment of the trough by unskilled persons, the clamping-screw 18 has its head provided with a transverse opening 18, adapted to receive anail or apiece of Wire by which it can be turned.

W'here the clamp8 is connected With the trough, as shown and described, it will be screwed tight to position to prevent any turning of the trough therein and the clamp will be made to fit sufficiently close to the pipe 3 to prevent any swiveling thereof. These results may be obtained, however, in other ways without affecting the essentials of my invention. It will also be observed that the upper end of the threaded aperture for the valve 20 is above the maintained level of the oil in the trough, so that a tight joint or astufiing-box for the stem of the valve is unnecessary, which simplifies and cheapens the construction.

In operation the user regulates the flow of the oil to the trough, and thereby the size of the flame, by turning the combustion-section, which in turn rotates the valve. When desired, in the construction here shown the valve may be widely opened for flushing the oil-passages to remove slight obstructions, or the valve can be readily and quickly entirely removed for any desired purpose.

I do not desire to limit myself to the exact arrangement and construction of parts herein shown and described, for modifications in arrangement and construction can be made without departing from the scope and spirit of my invention so long as the essentials thereof are present.

The construction of the clamping feature 8 and its coacting parts forms no part of the invention which is made the subject-matter of this application or the patent to be issued burner and valve beingoperatively connected and thereby adapted to move together.
